Graphene as an active virtually massless top electrode for RF solidly mounted bulk acoustic wave (SMR-BAW) resonators

, 2018
Mechanical and electrical losses induced by an electrode material greatly influence the performance of bulk acoustic wave (BAW) resonators. Graphene as a conducting and virtually massless 2D material is a suitable candidate as an alternative electrode ...

A two‐photon fluorescence micro‐spectroscopy method for chemotaxonomic characterization of fossil resins

Applications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Amber, a fossilized chemical defensive exudate, is important for understanding ancient plant–insect/pathogen interactions, yet its botanical origins, especially for Cretaceous amber, remain enigmatic. Here, we develop and apply a fluorescence micro‐spectroscopy approach within the context of a larger study on the provenance of amber ...

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

Advanced Science, Volume 13, Issue 12, 27 February 2026.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Fabrication of Bulk Acoustic Wave Resonator with Multilayer Graphene Electrode

physica status solidi (b), Volume 262, Issue 12, December 2025.
Herein, multilayer graphene structures are grown on the silicon substrate for the fabrication of the bulk acoustic wave resonator device. The result reveals that both methods can be used to replace the Bragg reflector. Two bulk acoustic wave resonator (BAW) devices with multilayer graphene as bottom electrodes are fabricated using the chemical vapor ...
